[0002] High-density aluminum honeycomb means that the density of the honeycomb is not less than 192kg / m 3 The aluminum honeycomb core material is characterized by a small honeycomb aperture (≤3.2mm) and thick aluminum foil used in its preparation (≥0.08mm). The strength and modulus of high-density aluminum honeycombs are much higher than those of ordinary aluminum honeycombs, and they are widely used in commercial aircraft engine nacelle systems. Since the high-density aluminum honeycomb has a small aperture and thick aluminum foil used in its preparation, the tensile force required for the cell expansion is much greater than the bonding strength of the honeycomb nodes, so it cannot be prepared using the traditional stretching method. The corrugation method is to pre-prepare the aluminum foil into a semi-hexagonal corrugated sheet, and then stack the semi-hexagonal corrugated aluminum sheets one by one according to the hexagonal hole pattern, and prepare them by clamping and hot pressing. After the corrugated aluminum foil is clamped, the honeycomb cells have been formed, and the size of the honeycomb block is large. The traditional flat hot press cannot be heated evenly for hot pressing and curing. Therefore, it is necessary to invent a corrugated formed aluminum honeycomb clamping and pressurizing device to clamp the aluminum honeycomb blank and apply a quantitative pressure to facilitate the subsequent transportation to the oven for heating and curing the honeycomb block.

[0045] In some embodiments, the parallelism between the top plate 11, the bottom plate 12 and the clamping and pressing plate 3 is no higher than 0.2 mm.

[0046] In some embodiments, the pressure loading of the separate hydraulic station 21 is manual or electric.

[0047] The main frame 1 is composed of two high-strength metal plates, a top plate 11 and a bottom plate 12, and four metal guide columns 13. The four metal guide columns 13 are vertically fixed at the four corners of the bottom plate 12 and are connected and fixed to the top plate 11 to form a stable clamping and loading frame structure that can place honeycombs and install the clamping and pressure plates 3. The space formed by the clamping and pressure plates 3 and the bottom plate 12 is used to place the honeycombs to be processed.

The parallelism between the clamping and pressurizing plate 3 and the bottom plate 12 is not higher than 0.2mm.

[0050] The pressure locking device 6 is used to lock and maintain the pressure load of the hydraulic cylinder 22 on the clamping pressure plate 3. After the pressure loading device 2 is withdrawn, the target load can still be maintained and locked. When the hydraulic cylinder 22 is separated from the cylinder fixing ring 4, the pressure load applied to the honeycomb material block remains unchanged. The pressure locking device 6 is composed of four metal wire rods 61, a pressure equalizing pad 62, and a wire rod nut 63.

When the limit spring 7 reaches the supporting height, the limit ring 8 is tightened.

[0053] like Figure 4As shown, the operation process of the corrugated formed aluminum honeycomb clamping and pressurizing device provided in the embodiment of the present application is as follows: check whether the clamping tool body and the pressure loading device are intact, check whether the clamping and pressurizing plate are parallel and whether the lifting and lowering are smooth; raise the clamping and pressurizing plate to a position higher than the height of the material block according to the height of the material block, use the limit spring to support the clamping and pressurizing plate, and use the limit ring to lock the feeding height; place the high-density aluminum honeycomb blank material block to be clamped and pressurized in the center of the main tooling, then loosen the limit ring and lower the limit spring to the low position; use the cylinder fixing ring at the top plate to connect and lock the cylinder of the pressure loading device; start the manual / electric hydraulic tool The hydraulic station is set up to make the cylinder piston apply pressure load to the clamping and pressure plate, and the load size is controlled by the instrument on the hydraulic station; after the applied load meets the process requirements, the pressure locking device is tightened with a torque wrench, and the four screws maintain the same tightening torque to fix the position of the clamping and pressure plate; the quick-release locking collar on the cylinder is rotated to separate the cylinder from the top plate of the clamping fixture; the clamping fixture with material is placed in the oven to solidify the honeycomb material block; after the solidification is completed, the fixture with material is taken out, the pressure locking device is loosened with a torque wrench, the material block is taken out, and the honeycomb clamping and hot pressing process is completed; if multiple sets of clamping fixtures are working at the same time, the above steps are repeated.

[0054] The corrugated aluminum honeycomb clamping and pressurizing device provided in the embodiment of the present application can meet the requirements of quantitative clamping and pressurizing during hot pressing and curing of aluminum honeycombs prepared by the corrugated forming method. The frame-type flat plate clamping and pressurizing design is adopted, and the clamping pressure is quantitatively controlled in cooperation with the separate hydraulic station. The assembly is simple and efficient. One hydraulic station can be used with multiple sets of clamping and pressurizing tooling at the same time, which can meet the requirements of clamping and pressurizing of high-density aluminum honeycomb blanks. The main frame adopts a four-column structure, which is convenient for the filling of honeycomb blank blocks and the lifting and pressurizing of the clamping and pressurizing plate. A cylinder fixing ring is designed at the top plate of the main frame to provide a docking interface for connecting the hydraulic station. The pressure loading device adopts a separate structure of the hydraulic station and the hydraulic cylinder body, which is convenient for the hydraulic cylinder to realize flexible pressurization on the honeycomb material block. A quick-release locking collar is designed on the hydraulic cylinder body to realize quick locking and assembly connection with the cylinder fixing ring on the top plate of the clamping main frame. The hydraulic station can be driven manually and electrically, and the hydraulic station is equipped with an instrument display, and the clamping pressure can be quantitatively controlled.

[0055] The clamping and pressurizing plate is connected to the four columns of the main frame through linear bearings, so that the clamping and pressurizing plate can smoothly lift and lower to clamp the honeycomb, and the linear bearings can ensure that the clamping and pressurizing plate is relatively parallel to the bottom plate of the main frame. The pressure locking device is used to lock the load force applied by the pressure loading device to the clamping and pressurizing plate. After the hydraulic cylinder body is disassembled, the aluminum honeycomb blank is still kept with a quantitative clamping force, which is convenient for the clamping and pressurizing tooling to enter the oven for high-temperature curing operation after being separated from the pressure loading device. An elastic pressure-compensating device is designed at the pressure-equalizing pad of the pressure locking device to ensure that the honeycomb blank can continue to be pressurized due to the change in the size of the material block due to heat when it is heated and cured in the oven, thereby ensuring the quality of honeycomb curing. The limit spring is used to support and limit the position of the clamping and pressurizing plate, which is convenient for production operation. The device has a simple structure and is suitable for clamping and pressurizing aluminum honeycombs formed by corrugated process. It solves the problem of quantitative clamping and pressurizing of aluminum honeycomb blanks prepared by corrugated forming method before curing, and improves the efficiency of honeycomb curing preparation.
